瑞利波探测公路施工隧道地质灾害的可行性分析

Feasibility analysis of detecting geological disaster for tunnel construction by RayleighWave technology

瑞利波探测是一种原位测试的工程地震探测技术,其频散曲线的变化与地下地质条件存在联系,通过频散曲线的特征识别,可得到探测方向上一定范围内的地质构造情况;瑞利波在介质中的传播速度与介质的工程物理特性有关,据此可对探测范围内岩土的物理力学性质做出评价。本文针对公路隧道施工过程中普遍存在的地质问题,结合瑞利波的探测原理,论述了瑞利波探测公路隧道施工地质灾害的可行性。

RayleighWave detect is one original place test of engineering seismic technology. The changes on its frequency- Disperse Curve are related to the geological conditions. We can detect the geology structures in the certainty scope on the detecting orientation by identifying the characteristics of the Frequency-Disperse Curve. The spreading velocity of the RayleighWave in the media is related to its engineering and physical characteristic. On this basis we can estimate the physical mechanics quality of the rock in the detecting scope. This paper discussed the feasibility of detecting geological disaster for road tunnel construction by using RayleighWave technology, aiming at the public problem in the course of tunnel construction and combining RayleighWave detecting theory.
